Engineering Contradiction Analysis
1Reliability
If wheel impact sensing systems are used to detect tire damage, then tire damage detection capability is provided, but the system complexity increases and reliability is insufficient
Solution Approach 1:
The patent extracts the tire damage detection function from complex multi-sensor impact sensing systems and implements it through a simplified approach using only existing wheel speed sensor data. By taking out the essential detection function and removing unnecessary system complexity, the invention achieves reliable tire damage detection while avoiding the drawbacks of complex device architecture.
2Measurement precision
If normalization of wheel speed data is performed to improve detection accuracy, then measurement precision is improved, but processing time increases
Solution Approach 1:
The patent applies preliminary normalization processing to wheel speed data by comparing current wheel speed with historical average wheel speed data. This preliminary action of normalizing data against established baselines enables rapid real-time detection without requiring complex computational processing, thus improving measurement precision while minimizing processing time loss.
3Loss of time
If real-time detection is implemented to promptly identify tire damage, then response time is reduced, but system complexity and computational requirements increase
Solution Approach 1:
The patent implements a self-service detection mechanism where the system automatically compares current wheel speed measurements with pre-stored historical average data and automatically generates damage alerts when anomalies are detected. This self-service approach enables real-time detection without requiring complex external processing systems, reducing both response time and system complexity by making the detection system autonomous and computationally efficient.
